Baja California, officially the Free and Sovereign State of Baja California, is a state in Mexico. It is the northernmost and westernmost of the 31 states which, with the Federal District, comprise the 32 Federal Entities of Mexico. Before becoming a state in 1953, the area was known as the North Territory of Baja California. The mainland portion of the state is bordered on the west by the Pacific Ocean, on the east by Sonora, the U.S. State of Arizona, and the Gulf of California (also known as the "Sea of Cortez"), and on the south by Baja California Sur. Its northern limit is the U.S. state of California.
Baja California is the twelfth largest state by area in Mexico. Its geography ranges from beaches to forests and deserts. The backbone of the state is the Sierra de Baja California, where the Picacho del Diablo, the highest point of the peninsula, is located. This mountain range effectively divides the weather patterns in the state. In the northwest, the weather is semi-dry and mediterranean. It is in this area where a few valleys can be found, such as the Valle de Guadalupe, the major wine producing area in Mexico. The state is also home to numerous islands off both of its shores. In fact, the westernmost point in Mexico, the Guadalupe Island, is part of Baja California. The Coronado, Todos Santos and Cedros Islands are also on the Pacific Shore.
